As others have already pointed out, the assembler cannot fill in
the address because it does not yet know where a possible following
link might put the generated code.

You can use avr-objdump to look at the relocation information,
just look at the following paragraph. There the relocation information
is printed as:
        2: R_AVR_16     .text+0x2
           ^--- type    ^--- address, put this two bytes in the .text segment
